Overview
The COP8SAB720M9 is a 2k OTP EPROM microcontroller from the COP8SA family, featuring an 8-bit architecture with 128 bytes of RAM and 16 I/O pins. It operates within a temperature range of 0°C to +70°C and supports a supply voltage of 2.7V to 5.5V. The device utilizes a 20-pin DIP package and includes features such as low EMI design, power-on reset, and MICROWIRE/PLUS serial interface.
Feature Summary
- Low electromagnetic interference (EMI) design for quiet operation
- One-time programmable (OTP) memory with read/write protection
- Multi-input wakeup logic with optional interrupts
- User-selectable clock options including internal R/C oscillator
Applications
- Low-cost embedded control systems
- Battery-powered devices requiring low current drain
- Applications needing high pin efficiency in small packages
Procurement Notes
Verify the specific ordering suffix '20M9' against the manufacturer's official documentation to confirm the exact package type, temperature rating, and OTP configuration. Ensure compatibility with existing development tools if upgrading from ROM-based variants.
Selection Notes
Select this component when a cost-effective 8-bit solution with OTP flexibility is required. It serves as a direct replacement for COP800 series devices in new designs, offering enhanced features like low EMI and power-on reset while maintaining pin and instruction set compatibility.
Part Context
Part of the COP8SA family, which provides supersets of the legacy COP800 architecture. This family emphasizes code efficiency through single-byte instructions and modified Harvard architecture, allowing direct access to data tables stored in program memory.
Replacement Considerations
COP8SAB720N9 (DIP-20, -40 to +85°C)
